Federal Way will add speed cameras at a third school zone – Panther Lake Elementary – starting Monday.

Warnings will be issued for the first month in the Panther Lake Elementary school zone in the 34500 block of First Avenue South. Ticketing will start Jan. 7, said Federal Way police spokeswoman Cathy Schrock.

Federal Way already has school zone speed cameras at Saghalie Middle School and Twin Lakes Elementary. The city also has red light cameras at three intersections.

Schrock said Panther Lake is being added because of high traffic volumes on four-lane First Avenue South and a high number of speeding infractions in the school zone. “It’s a very busy area,” Schrock said.

The fine for speeding in a school zone ranges from $210 to $250, depending upon how much a driver is speeding over 20 mph.

Schrock said the police department will start warning and eventually ticketing at 26 mph with the cameras at Panther Lake Elementary, allowing for a margin of error in speed measurements. Patrol officers use the same standard when issuing speeding tickets in school zones, she said.

The school zone cameras operate when students are traveling to and from school, during the lunch hour, and at any time when the flashing yellow school zone lights are on, Schrock said.
